Built for Constellation Software
The Payments Engine
Built For You
CSIPay Gateway is Constellation Payments’ embedded payments platform, built exclusively for Constellation Software and Jonas Group operating companies. Integrate payments directly into your product, without building or managing the infrastructure yourself.
Why CSIPay?
The shared payments platform that eliminates duplication and accelerates go-to-market
The Challenge
Independent Development
Building payments independently demands significant investment before you go live. Compliance, processor integrations, risk management, and merchant underwriting all fall on each operating company to solve alone.
Fragmented implementations
Increased risk
Compliance overhead
Processor integrations
Risk management
Merchant underwriting
The Solution
Centralized Platform
CSIPay centralises payments as a shared platform across the Constellation ecosystem. Integrate once and access processing, compliance, risk controls, and settlements, so you stay focused on your product.

The Bottom Line
